HOSE OR PIPE COUPLING.

SPECIFICATION forming part of Letters Patent No. 706,847, dated August12, 1902.

Application filed April 10, 1902. Serial No. 102,247. (No model.)

To aZZ whom it may concern; 1

Be it known thatl, HENRY A. F. PETERSEN, a citizen of the United States,residing at the city of New York, in the borough of the Bronx, in thecounty and State of New York, have invented certain new and usefulImprovements in Pipe or Hose Couplings, of which the following is afull, clear, and exact specification.

My invention relates to means for uniting the ends of hose or soft-metalpipes of any.

kind; and said invention has for its object more particularly to providea simple, reli: able, and inexpensive apparatus which is so constructedthat the same may be readily and easily applied to the opposing ends ofthe; hose or pipe to be united when it is desired of reference indicatelike parts, Figure 1 is a side View showing the opposing ends of a hose.

or pipe with a coupling made according to and embodying myinventioriready to be secured thereto. Fig. 2 is a similar view showing thecoupling with the ends of the hose onpipe duly secured together thereby,and Fig. 3 is a top view of the apparatus as seenin side View at Fig. 2.

In said drawings, Adesignates the coupling,

comprising the sleeve B, having the tapering ends 0 O and the flatcentral portion 13,111- termediate said tapering ends, provided upon itsopposite side with bosses a a, said tapering ends 0 0 being adapted toreceive the opposing ends of the hose or pipe sections E E to be united.Upon the opposite sides of the sleeve B to the square bosses d a thereonis pivotally secured by rivets or screws 1) b the locking device,comprising the double levers F F, which are substantially S shaped inoutline and secured together near their outer ends bythe'connecting-sections G G.

H H denote annular clamps or collars, which are adapted to embrace thetapering ends 0 Got the sleeve B and the ends of the hose or pipethereon, and II denote links, the outer "ends 'of which arepiv'otallysecured to the outer opposite sides of the clamps or collars HH by screws or rivets c c and their inner ends similarly secured to theends of the S- shaped levers F F upon the inner sides thereof by rivetsor screws d d, and e 6 denote toes provided on said links adapted tocontact with the sides of the square bosses a a, whereby to aid inholding the apparatus to its locked position.

The operation of the apparatus is as follows: The apparatus is firstopened to about the position indicated at Fig. 1, and the opposing endsof the hose or pipe to be united are passed through the clamps orcollars H H and then forced upon the tapering ends C (J of the sleeve Bto about the position indicated in the drawings. The clamps or. collarsH H are then pushed toward each other until the same are in positionupon the tapering ends 0 G of the sleeve 'B, whereupon the lockingdevice is forced downward in the direction of the arrow, Fig. 1, and thelinks I I caused to draw the clamps or collars H H farther inward andfirmly clamp the ends of the hose or pipe upon the tapering ends of saidsleeve B .and lock said clamps or'collars in position to effect aperfect union of the parts.

It is to be observed that inasmuch as the apparatus is a complete onerequiring no as sembling or setting together or calling for the use ofany tools in order to apply the same it is particularly adapted forquickly and effeotivel yuniting sections of hose or soft-metal 'pipewhenever it is desired to increase the length of said hose or pipe orrepair a break therein.

Without limiting myself to the details of construction, which may bevaried 'within the scope of the invention, whatIclaim, and desire tosecure by Letters Patent,'is-

1. A coupling comprising a sleeve adapted to receive the ends of pipe,annular clamps adapted to embrace the ends of the sleeve and the pipethereon, and a lever pivotally connected to said sleeve and annularclamps for locking said annular clamps in position upon said sleeve,substantially as specified.

2. A coupling comprising a sleeve adapted to receive the ends of pipe,annular clamps adapted to embrace the ends of the sleeve and the pipethereon, and a lever pivotally secured intermediateits ends to saidsleeve and at its ends to the annular clamps and adapted to lock saidannular clamps in position upon gheiends of said sleeve, substantiallyas speci- 3. A coupling comprising a sleeve adapted to receive the endsof pipe, collars adapted to embrace the ends of the sleeve and the pipethereon, a double lever pivotally secured to said sleeve,and linkspivotally secured to said collars, and the ends of said dou ble lever,substantially as specified.

4. A coupling comprising a sleeve having tapering ends adapted toreceive the ends of pipe, collars adapted to embrace the tapering endsof the sleeve and the pipe thereon, a locking device comprising twolever members united together at their ends, and pivotally securedmidway between their ends to the sleeve, and links pivotal] y secured tothe ends of said lever members, and the collars, substantially asspecified.

5. A coupling comprising a sleeve having tapering ends adapted toreceive the ends of pipe, collars adapted to embrace the tapering endsof said sleeve and the pipe thereon, a locking device comprising twosubstantially S-shaped members united at their ends, and pivotallysecured midway of their ends to said sleeve, and links having their endspivotally secured to the endsof said S-shaped members and to theopposite surfaces of said collars, substantially as specified.

6. A coupling comprising a sleeve having tapering ends adapted toreceive the ends of pipe, square bosses arranged upon the opposite sidesof said sleeve intermediate its ends, collars adapted to embrace thetapering ends of said sleeve and the pipe thereon, a locking devicecomprising two substantially S- shaped members united at their ends andpivotally secured midway of their ends to the square bosses on saidsleeve, and links having their ends pivotally secured to the ends ofsaid S-shaped members and to the opposite sides of said collars andprovided with toes adapted to contact with the sides of said squarebosses, substantially as specified.

Signed at the city of New York, in the county and State of New York,this 8th day of April, 1902.
